Retail giant Target Corp and sportswear firm Umbro have both recalled clothing and footwear items bearing neo-Nazi slogans after being alerted by furious shoppers.

Minneapolis-based Target, one of the largest discount chains in the country, has ordered its 1,100 stores to remove shorts and baseball caps marked "eight eight" or "88" - code among white supremacists for 'Heil Hitler' because H is the eighth letter of the alphabet.

It was alerted to the problem by Californian shopper Joseph Rodriguez and the Southern Poverty Law Center, a national organisation that tracks racist groups.

According to the Sacramento Bee, the clothing was manufactured by Utility, one of Target's private labels.

In a separate incident, sportswear firm Umbro apologised on Wednesday after Jewish groups complained at the name of one of its running shoes - Zyklon - a lethal gas used by Nazis to kill millions of Jews during the Second World War.

Umbro has agreed to ditch the offending name, which appeared in adverts and on the shoes' boxes rather than the trainers themselves, amid claims of "appalling insensitivity" from outraged Jewish groups.

Dr Shimon Samuels, of the Simon Wiesenthal Centre, told Umbro CEO Peter McGuigan in a letter that naming a product after a deadly gas used to kill countless innocent men, women and children was "an encouragement to neo-Nazis and skinheads who terrorise the football terraces and a dishonour to sport itself".

An Umbro spokesman said: "We regret that there are people who are offended by the name. The naming of the shoe is purely coincidental and was not intended to communicate any connotations."
